ApplicationJanuary 24, 1958, Serial No. 710,883 2 Claims. (Cl. 30-47)The improvement pertains to a safety razor which comprises a flat,substantially rectangular blade which along one side is mounted in atubular member, said blade being in a radial relation thereto, acombined guard and holder for reception of the blade with its tubularmember, and a handle upon which the holder may be mounted for operativeuse of the blade.

The blade with the holder are of such construction that they may beusedselectively in one of two positions. In one of them the holder, with theblade carried therein, is disposed at right angle to the handle. In theother position the handle fits into one end of the tubular membercarrying the blade so that the blade may be used in the manner ofstraight razor, either for shaving'or for the purpose of having theblade honed.

My improvement includes novel means whereby the position of the blade,or, more specifically, the position of the cutting edge of the bladewith respect to the guard of the holder, may be adjusted to the bestshaving angle.

I shall now describe my improvement with reference to the accompanyingdrawings in which:

Fig. 1 is a perspective view of my improved razor;

Fig. 2 is a front elevational view thereof;

Fig. 3 is 'a vertical sectional view on line 3-3 of Fig. 2;

Fig. 4 is a similar sectional view disclosing component elements of therazor in difierent operative positions than shown in Fig. 3;

Fig. 5 is a sectional view on line 5-5 of Fig. 3 of the head structureof the razor, the view including a handle in a position difierent fromthat shown in Fig. 3.

Similar numerals refer to similar parts throughout the several views.

The blade which is to be used in the razor is marked 12. It ispreferably thin, being of uniform thickness all along its body, with theexception of, the marginal operative portion 13 which. tapers to acutting edge 14. At the side opposite to that provided with the cuttingedge, the blade includes two tongues 15 extending from the body portionof the blade but disposed in the same plane. The blade is joined to atubular member 17 which is of the same length as the blade and which isprovided with a pair of radial slots 16 for reception of said tongues.These may be held frictionally by the opposed walls of the respectiveslots, or may be soldered in place so that the blade and the tubularmember 17 will form a unit.

At one end the tubular member is threaded axially, as best shown at 18in Fig. 5. In addition thereto, said tubular member contains a threadedradial bore 19, this being located intermediate the ends of said member17.

The holder, generally identified by numeral 10, may be made of sheetmetal stock. It consists of a rectangular base 20 which along one sideincludes a downwardlydepressed lip 21, while at the opposite side ofsaid base the holder is formed into a loop 22. The loop is circular incross-section, but short of completing a full circle, so that a gap 23is left between the upper surface of the base and the free end 24 of thesaid loop.

Normally, the blade rests on the base, its cutting edge If the holder 10with the blade carried therein is to,

be used at a right angle position with respect to the handle 11, thethreaded end 26 of the handle is screwed through the slot 25 in thelooped portion 22 of the holder 10 into the radial bore 19 in thetubular member-'17. It will be noted that the handle includes an annularflange 27 which bears against the outer surface of the loop 22. As theend 26 of the handle. is screwed into the bore 19, the flange 27tightens the contact between the inner surface of the loop and thetubular member 17 so that the blade, which projects from said tubularmember, will be held firmly in its position with relation to the base20. The normal position of the blade with respect to the base is shownin Fig. 3. In this connection, attention is invited to the spacingbetween the blade 12 and the free end 24 of the loop 22 above saidblade.

As the blade, designed for long continuous use, is adapted to be honedrepeatedly, the distance of the cutting edge 14 from the outer end oflip 21 may increase, this being due to abrasion resulting from saidhoning. In such a case it may be necessary to adjust the position of thelip 21 of the holder to the cutting edge of the blade so as to retainthe best operative angle of the blade for shaving purposes. Theoperative angle is indicated in Figs. 3 and 4 by a line xx contactingthe outer end of the lip 21 and the outer end of the blade.

The adjustment is effected by a limited turn of the holder 10 about thetubular member 17 so as to lower the base 20 from contact with theblade, as shown in Fig. 4. As a result, the outer end of the lip woulddescribe an arc downwardly and towards the handle 11, so that theoperative angle of the blade would be {th same as shown in- Fig. 3.

It will be understood that in order to efiect such an adjustment itwould be first necessary to loosen the frictional contact between theloop and the tubular member 17. This may be done by slightly unscrewingthe end 26 of the handle 11 from the threaded bore 19 in said tubularmember 17. On completion of the adjustment a turn of the handle aboutits axis would serve, by means of the flange 27, to bring the loop 22back into a tight frictional contact with the member 17 so that theblade would be held firmly in its relative position to the base 20.

It will be understood that some changes may be made in the structure ofthe razor and the component partsthereof without departing from theinventive concept disclosed herein.

What I, therefore, wish to claim is as follows:

1. A razor comprising a holder consisting of a flat, substantiallyrectangular base having at one side a downwardly-depressed lip and beingat the other side formed into a cylindrical loop, the wall of the loopbeing provided, intermediate its ends and below the level of the base,with a slot extending transversely to the axis of the loop, a tubularmember axially fitting into the loop, a. blade radially extending fromthe tubular member over the base and extending to a line spaced from thelip, said tubular member being provided with a threaded radial bore inregister with the slot in the cylindrical loop, a handle having athreaded end portion adapted to be threaded into the bore through theslot in the loop, an annular flange on the handle, the flange bearingfrom outside against the outer surface of the loop and ser ing 3 tosecure the tubular member and the base of the loop in a locked position.

2. A razor comprising a holder consisting of a fiat, substantiallyrectangular base having at one side a downwardly-depressed lip and beingat the other side formed into a cylindrical loop having a free endspaced from the upper surface of the base, the Wall of the loop beingprovided, intermediate its ends and below the level of the base, with aslot extending transversely to the axis of the loop, a tubular memberaxially fitting into the loop but being capable of a limited rotarymovement about its axis, a blade radially extending from the tubularmember over the base and extending to a line spaced from the lip, saidtubular member being provided with a threaded radial bore in registerwith the slot in the.

cylindrical .loop, a handle having a threaded end portion 4 adapted tobe threaded into the socket through the slot in the loop, an annularflange on said handle, said flange bearing from outside against theouter surface of the loop and serving to secure the tubular member andthe base of the loop in a locked position.
